Description

General description

Pyridoxal is a derivative of vitamin B₆.[1] Vitamin B₆ derivatives contain a core pyridine ring. Pyridoxal consists of an aldehyde group at pyridine′s 4′ position.[2] Pyridoxal is a water-soluble vitamin.[3]

Application

For the labeling of amino acids and their detection in picomolar amounts; Coenzymes and Cofactors, vol. 1: Vitamin B₆, Pyridoxal Phosphate

Biochem/physiol Actions

Vitamin B₆ derivatives are initially oxidized to pyridoxal. It is then phosphorylated to pyridoxal 5′- phosphate (P5P). Pyridoxal 5′- phosphate is the circulatory form of vitamin B₆.[1]
